how do I import csv file into icloud

It has to be converted to a compatible vCard file first (and Outlook can't export a compatible one, if that's what you're using). Easiest thing to do is create a Gmail account, then import your CSV file to Gmail (see https://support.google.com/a/answer/14024?hl=en), then export the contacts from Gmail as a vCard (see https://support.google.com/mail/answer/24911?hl=en) and import it to iCloud (see http://support.apple.com/kb/PH3605).

Great help. Worked perfect and was very easy to do.

Thank you

Thank you for such clear steps. I was able to finally import my contacts after looking high and low on the internet and reading forums that were useless!
